DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Refer to the attached instructions Figure 1-2 The utility model is an environmentally friendly sewage treatment device, comprising a housing 1, see Figure 1 , the water inlet pipe 2 is fixedly installed inside the shell 1, see Figure 2 The inside of the water inlet pipe 2 is rotatably connected to the fan blade 3, and the inside of the fan blade 3 is connected to the reciprocating screw rod 4 through a threaded connection. The reciprocating screw rod 4 is inserted into the inside of the water inlet pipe 2, and the end of the reciprocating screw rod 4 is fixedly connected to the connecting rod 5. The outer wall of the connecting rod 5 is fixedly connected to the gear rod 6, and the gear rod 6 is slidably connected to the inside of the shell 1. One side of the gear rod 6 is engaged with a gear 7, and the gear 7 is rotatably connected to the inside of the shell 1. The outer wall of the gear 7 is fixedly connected to the plug rod 8, and the outer wall of the plug rod 8 is sleeved with a connecting block 9;

[0020] A guide slot 10 is provided inside the shell 1, and the connecting block 9 is slidably connected to the inside of the guide slot 10. A scraper 11 is fixedly connected to the outer wall of the connecting block 9, and a filter screen 12 is provided at the bottom of the scraper 11. The filter screen 12 is fixedly installed inside the shell 1. A collection box 13 is provided on the outer wall of the filter screen 12, and a support plate 14 is provided at the bottom of the collection box 13. The support plate 14 is slidably connected to the inside of the shell 1, and a pressure spring 15 is fixedly installed at the bottom of the support plate 14. The outer wall of the support plate 14 is fixedly connected to the outside of the shell 1. The pressure piece 16 is slidably connected to the inside of the shell 1, and an alarm 17 is provided at the bottom of the pressure piece 16. The alarm 17 is fixedly installed inside the shell 1.

[0021] It should be noted that, when the water inlet pipe 2 is connected to the sewage pipe, the sewage is discharged into the filter screen 12 inside the shell 1 through the water inlet pipe 2, and the filter screen 12 is used to filter the sewage, so that impurities in the sewage are filtered and accumulated on the filter screen 12, and the sewage after filtering will continue to fall through the filter screen 12 and be discharged through the drain port of the shell 1 to enter the subsequent processing steps. In the process of sewage falling onto the filter screen 12 through the water inlet pipe 2, the sewage will push the fan blade 3 to rotate, so that the fan blade 3 drives the reciprocating screw rod 4 to perform linear reciprocating motion, thereby causing the reciprocating screw rod 4 to reciprocate through the connection The rod 5 pulls the gear rod 6 to perform linear reciprocating motion, so that the gear rod 6 drives the gear 7 to rotate back and forth. The rotation of the gear 7 drives the plug rod 8 to rotate, so that the plug rod 8 drives the connecting block 9 to slide along the inside of the guide slide 10, and then the connecting block 9 drives the scraper 11 to move along the curved surface of the filter screen 12, scraping and pushing the impurities accumulated on the filter screen 12, so that the scraper 11 scrapes and pushes the impurities accumulated on the filter screen 12 into the inside of the collection box 13, so as to achieve the effect of automatically cleaning the impurities accumulated on the filter screen 12, and does not need an external power supply to control the operation of the sewage treatment device, making the device more energy-saving and environmentally friendly;

[0022] Furthermore, the openings on the scraper 11 allow the wastewater on the filter 12 to flow through the openings on the scraper 11 when the scraper 11 pushes the impurities on the filter 12, thereby preventing the scraper 11 from pushing all the wastewater on the filter 12 into the collection box 13, thereby affecting the normal operation of the collection box 13. Due to the openings on the collection box 13, some wastewater that enters the collection box 13 along with the impurities gradually seeps out through the openings, thereby reducing the water content inside the collection box 13.

[0023] Furthermore, as the amount of impurities accumulated inside the collection box 13 increases, the collection box 13 will gradually squeeze the support plate 14 downward, causing the support plate 14 to squeeze the pressure spring 15 to contract and gradually drive the pressure piece 16 downward, and finally causing the pressure piece 16 to press on the switch on the top of the alarm 17, causing the alarm 17 to sound an alarm and transmit the signal to the staff's work equipment, reminding the staff to clean the impurities inside the collection box 13 to prevent excessive impurities inside the collection box 13. The impurities on the filter screen 12 cannot enter the interior of the collection box 13, causing impurities to accumulate on the filter screen 12, affecting the filter screen 12's efficiency in filtering sewage. It should be noted that when the pressure piece 16 presses the switch of the alarm 17, the support plate 14 will drop and contact the bottom of the inner wall of the outer shell 1, and will be unable to continue to drop, preventing the pressure piece 16 from continuing to drop and crushing the alarm 17.
